This is not an issue of HYDRUS anymore. HYDRUS cares only about the working folder and the level_01.dir file with the path to the working folder. The error you get indicates that HYDRUS cannot find one or the other. J.

Start according to FAQ 4, i.e., with a single project, before running projects in a batch. Test it first at a desktop, before moving to a network, etc. J.

Obviously, make a back up first so that you can return to the original file if needed. J.

Interception and snow cannot be used simultaneously, only one or the other. J.

I think you should try to understand when the water/solute fluxes are negative and when positive, and what different solute BCs actually do. It is all explained in the manual. J.

Perhaps, I should have posted the 32 bit version of the file. J.

I must have already fixed that in my latest files since I do not see this behavior. Replace the attached file (note that this is 64-bit exe). J.

You need to make sure that your boundary conditions are physical meaningful. The constant head BC (position of GWT) allows for flow in both direction (downward recharge or upward discharge) depending on the development of the pressure head profile (and atmospheric BC at the top). The zero-concentrat...

You should be able to figure this out yourself based on the information that I provided in my previous answer. J.

HYDRUS automatically normalized whatever is entered. J.

To limit the size of output files, I try not to print things that can be easily calculated from existing output. Indeed, the sorbed concentration can be easily calculated using the adsorption isotherm, e.g., s=Kd*c. Note that s is in units of [Mass_contaminant/Mass_soil] and thus to get the mass for...

You can download an older version of the source code at the HYDRUS website and recompile it with new dimensions. J.

You can get different air-entry values if you use the modified van Genuchten model and manipulate the Theta_m (>Theta_s) parameter. The GUI allows only 250 print times. The computational module is dimensioned for 100 print times. If you want to have more than 250, but less than 1000, print times, yo...

As long as you do not expect ponding of the soil surface, both BCs should work the same. If you do, then you should use the atmospheric BC, which can deal with such conditions. J.

I do not have anything to add to my previous answer. J.
